Following the sixth beta updates of iOS 11.3 and watchOS 4.3 last week, Apple on Monday released the milestone macOS High Sierra 10.13.4 beta 6 to registered developers, along with other details.
Labeled build 17E190a, macOS High Sierra 10.13.4 beta 6 has been released and brings more stability, security, and compatibility improvements to your Mac. Registered developers running the previous beta can install it right now from the Updates pane in the Mac App Store.
If you're new to testing the macOS High Sierra Beta or Public Beta, you'll need to run the macOS Developer Beta Access Utility to download the latest macOS High Sierra 10.13 beta. Once installed, you'll automatically receive new macOS betas as they become available.
According to Apple, macOS 10.13.4 beta 6 can be installed on MacBook Late 2009 or later, MacBook Air Late 2010 or later, MacBook Pro Mid 2010 or later, Mac mini Mid 2010 or later, iMac Late 2010 or later, iMac Pro (2017), and Mac Pro Mid 2010 or later computers.
In addition to the sixth beta of macOS High Sierra 10.13.4, Apple today released the fourth beta of its upcoming macOS Server 5.6 operating system, which is available only to registered developers with a paid and active Apple Developer account, and the Apple Configurator 2.7 app for easy deployment of iPhone, iPad, iPod touch and Apple TV devices in organizations.
The macOS Server 5.6 beta 4 release addresses several issues, including the removal of the DEP script option from Profile Manager, errors encountered when exporting Wiki Server data, configuration profile installation failures during upgrades from macOS Server 5.2 to macOS Server 5.3, and some text theft errors and bugs.
